The present invention also provides a method of treating a subject in need of repair or replacement of an organ or a portion thereof; and/or a method of treating a subject with a disease or disorder which impairs or abrogates a liver, kidney, pancreas, thyroid or pituitary function. The present invention also describes an epithelial graft or artificial organ comprising spheroids, organoids or a combination thereof, and a kit for implantable epithelial graft formation comprising organoids.

Abstract: Highly sensitive imaging of diseased tissues such as cancer is attractive because it potentially allows for early tumor detection. One of the problems associated with conventional, low molecular weight imaging probes is the limited tumor: background ratio. To circumvent this, imaging probes were conjugated to polymeric carriers and were surprisingly found to accumulate specifically at cancer sites. This invention describes an innovative targeting strategy for the selective identification of solid tumors by means of polymer-NIR fluorochrome conjugates which accumulate selectively within cancerous tissue relative to normal tissue.

Abstract: The invention provides a process for the preparation of essential oil microcapsules comprising dissolving a di- or polyisocyanate into an essential oil, emulsifying the resulting mixture in an aqueous solution containing a di- or polyamine, and or a di or polyhydroxy compound to effect encapsulation of said essential oil through interfacial polymerization, whereby there is formed a polyurea and/or polyurethane film around the essential oil droplets which film enhances the stability of said essential oil, reduces its evaporation rate and controls its release rate when applied to a substrate.

Abstract: Apparatus for detection of human falls comprises: an acceleration detector, for detecting vibration events, typically placed on a floor, a microphone, located in association with the acceleration detector for detection of corresponding sound events, and a classification unit to classify concurrent events from the microphone and the acceleration detector, thereby to determine whether a human fall is indicated. If the event appears to be a human fall, then an alarm is raised.
